Application med January 23,

My invention is concerned with what I call atomizing cleaners, and it consistsrfun damentally of a hand implement adapted to be connected with a source of air or other 5 gas under pressure and having a nozzle through which said compressed airis discharged, together with a tube surrounding the nozzle and lrovided with an extension which may be p aced in a pail of kerosene l or other cleanslng iuid, so that when the air is permitted to escape through the nozzle, it carries with it a spray of the oil, which, strikingv the surface to be cleaned, carries away with 15 which accumulates on the part tobe cleaned, such, for instance, as the engine of an automobile. v

To illustrate my invention, I annex hereto a sheet of drawings, in which,-

90 Fig. 1 is a side elevation of my apparatus with an ordinary 'air chuck connected thereto; L

Fig. 2 is a central longitudinal section of the same;

Fi ,3 is a view similar to Fig. 1, but showing a modified construction, and m ied rtion being in central vertical section; Fig. 4 is a detail, on an enlarged scale, xon the line v4--4 of Fig. 2; and

Fig. 5l is a detail, on a still larger scale, on the line 5--5 of Fig. 2.

The body of the device is in the form of a small casing having three divergin tubular portions, the front end having a arge internally-threaded opening 11 therein, into which is screwed the nut 12 which is preferably circular in cross section and milled on its periphery, and has the tube 13 secured therein and extending outwardly therefrom.

The vni ple portion 14 is adapted to have the preibrably liexible tube 15 secured thereon in the customary manner, and -in use the end of the tube 15 is extended intol the can 16 of kerosene or'wha-tever cleaning fluid is employed.

In the simplest form of my invention, illustrated in Fig. 3, the third arm or portion has an internally-threaded aperture 17 into which is screwed the threaded end of 5 the nipple 18, whichhas the exible tube 19 fastened thereon and extending to any desired source of compressed air. The nipple 14has the passage 20 therethrough -opening into the part 11, so that the oil can How out yce through the tube 13, and the portion 17 has f it the dirt and grimev 1922. Serial N0. 531,303;

the fine passage 21 therethrough terminating in the iine tube l22 secured in the body an formed a continuation of the passage 21. This tube 22 extendsl out to the end of the tube 13, and preferably has the short helically-coiled Wire 23 secured thereon, and which co-operating with the 'inner surface of the tube 13 keeps them concentric. By screwing the nut 12 in and out, it will be obvious that the relative positions of the tubes 13 and 22 may be varied as is necessary to increase or diminish the amount of oil that will be sucked up through the tube 15 and out through the tube 13 y the -vacuum eiect produced by the compressed air rushin out through the tube 22. 'v

referred form of my invention, which is esigned primarily for use inv garages and other places where air chucks are employed, for the nipple 18, adapted t0 be connected to an ordinary tube 19, I substitute v,the nipple 24, likewise adapted to threaded into the opening 17, and having the hexagonal portion 25 to which can be applied, adjacent the disk 26, against which rests the packing ring 27, which ring is Supported on the reduced, outer, tubular end 28 of the nipple 24. There' is a passage 29 extending. entirely -through the part 24 and terminating 1n an enlarged portion 30, and extending across the outer end of this enlarged portion is the-bar 31, which cooperates -with the tubular end 32 of the chuck valve 33. The chuck 34, which is ada ted to be connected with lea ing to a source of compressed air, is a well known article of commerce, and, per se, forms no part of my invention. advisable to explain how the connection 24 co-operates with this chuck, I have illustrated its internal construction, be seen that the passage through the stem 36 opens into the hollow vbody 37 in the inner end of which is seated the helically-coiled expanding spring 38, the outer end of which co-operates with the reduced inner end 39' of the valve body 33. This body portion 37 has covering its preferably tapered outer end the rubber annulus 40, through which slides the tubular portion 32 of the valve 33. The valve 33 has the ta ered ange 41 adapted to co-operate with t e correspondingly truncated conical portion 42 of the ru ber ring 40 and the pressure of the spring 38 .normally holds the valve seated on the rubber,

a wrench the hose. 35

As it seems where it will f necessitated by the state of the prior art.

' Leashes so thatl the air cannot pass through the small port 43 located at the base ot the tube 82. The internally-threaded cap 44 screwed on the outer end of the body 34 clamps the ring 40 in place, forming an air-tight joint. i/Vhen the chuck is forced against theend 30, the cross piece 3l engages the end of the tube 32 and forces the valve back against the resistance of the spring 38 to the position shown in full lines in Fig. 5, Where it will be seen that the port 43 is opened and the air can How through the implement.

As it would be diiiicult to manipulate the apparatus if the chuck has to be held independently by one hand, l provide the body 10 with a pair of ears 45 in which is pivoted the yoke .or bail 46 .having the nut 47 at the outer end thereof, through which nut is threaded the thumb screw 48 which has the disk 49 on its inner end, which is adapted to co-operate with the back of the chuck 34, as seen in Fig. l. When the device is to be used with the chuck 34, the thumb screwV 48 is turned back until the chuck can be placed in position, and then it is turned down until the disk 49 engages the chuck, when the apparatus is ready for use, and when the air is to be applied, all that is necessary is to give the thumb screw 48 a few turns to yopen the valve in the chuck, and the valve, ofcourse, will remain open until it is automatically closed by the spring 38 when it is allowed to act by turning back the thumb nut 48. lit will be obvious that Athe parts 18 and 24 can be used interchangeably as conditions demand.

While li have shown and described my invention as embodied in the form which l at present consider best adapted to carry out its purposes, it will be understood that it is capableof modiications, and that l do not desire to be limited in the interpretation of the following claims except as may be `What l claim as new, and desire to secure by Letters Patent of the United States, is:
